Onboarding – Configuring the Controller / Extender operating mode
A Wallbox eM4 Twin Controller can be set up to control additional Extender wallboxes up to a total of 30 charge
points and is then responsible for the static or dynamic load management within the charging group, releasing and
blocking charging stations and much more.
The
Controller / Extender
operating mode is recommended for:
Medium to large charging parks in companies, in semi-public and public spaces, and in the housing industry
Charging groups in private and semi-public use for which central billing is required
If you selected the
Controller / Extender
option when selecting the operating mode (see
step 4
in the section "Set-
ting up communication via the ABL Configuration App"), you must set up the parameters below for all charge points
within the group after entering the password to protect the wallbox.
Parameter
Description
Network settings (Upstream)
This is where you can firstly specify whether you want to connect to a backend
and then whether you wish to establish this connection via WLAN, LAN or LTE.
Network settings (Downstream)
Specify here whether you wish the Controller to be connected to further Ex-
tenders and whether you want this connection to be established via WLAN or
LAN.
Grouping
You can add more Extender wallboxes to the Controller here and name them as
needed to create a charging group.
Static load management
Register additional Extender charging stations with the Controller and set the
maximum charging current per wallbox: here, the maximum available static
charging power is distributed evenly to all charge points in the charging group.
Dynamic load management
Set up the dynamic adjustment of the charging currents here, taking into ac-
count the building load. For this function, you will need the ABL Energy Meter,
which is available as an accessory.
Load shedding
Activate the function that allows external systems (e.g. under TAB 4100) to
temporarily limit or switch off the charging infrastructure. For this function, a
control cable must be connected to terminal
EN1
ing a control cable in accordance with VDE AR-N 4100" on page 34).
Backend settings
You can select a template here, provided your backend provider is stored in the
app’s database. Alternatively, enter the access and communication data for
your provider manually.
QR-Code / Login credentials
To complete the configuration, you can output the access data (WLAN SSID /
password) here as a QR code or write it down to make this information availa-
ble to the owner and/or operator of the wallbox.
Software update
Install a new software version for the
ABL Configuration App
here as soon
as there is one available.
To complete the configuration, tap the
Continue
button: The wallbox is now configured and offers the option to ad-
just the parameters just set as well as other operating parameters via the
Continue to Control Board
button.
You can also change individual parameters at a later date by editing the current configuration (see next section). If
you want to set up the entire charging group from scratch, you will need to perform a factory reset of the Controller
wallbox: This function is available via the Support button in the
ABL Configuration App
and resets the Controller
and all connected Extenders to their factory defaults.
